EnerMech has been awarded a contract by Exxon Mobil to deliver a complete flowline decommissioning package for the Hoover Diana development in the Gulf of America, according to a June 16 press release.
The contract marks EnerMech’s first major decommissioning campaign in the region.
The Hoover and Diana fields, about 160 miles south of Galveston, Texas, have been an offshore development since 2000. The project utilizes the once pioneering floating production deep draft caisson vessel technology and gained the world record for deepwater drilling and production depths.
The scope includes flushing, pigging and filling subsea pipelines to safely remove hydrocarbons and prepare for decommissioning. This involves flushing of the umbilical, pipeline flushing, and seawater fill operations for the subsea flowline loop, as well as nitrogen flushing via subsea vessel, coiled tubing services, and final seawater filling for the Northern Diana flowline.
“The Hoover-Diana project marks our first large-scale decommissioning engagement in the Gulf of Mexico, building on the strong relationship we’ve developed with Exxon Mobil in Guyana since 2018,” EnerMech CEO Chuck Davison said. “With many offshore assets reaching the end of their lifecycle, the decommissioning market in the Gulf of Mexico is expanding rapidly.”
